Under which conditions can I use diiodomethane for contact angle measurements?

04 February 2021 1 2K Report

Hi,

I need to make contact angle measurements on PTFE, ideally with diiodomethane. As you may know, the product is quite toxic (for repiratory system mostly). But my drope shape analyser is not under a hood or anything. So I worry about diiodomethane vapors in the lab wihch has no windows, only a big door. Even with adequate respiratory protection I find it dangerous as the DSA is not under ventilated hood. As I have never use this product, what would you advise me to do?

Thank you by advance.

In the past, we made measurements in a normal laboratory environment with a 3 micro-liter drop size for the diiodomethane. We had only standard laboratory PPE of latex gloves, lab coat, and safety glasses.
